No data since I renewed my contract - O2 keep having me do the same steps over and over

So at the start of September I Chose to upgrade my sim only package, going to an unlimited data one. I requested a new sim as I wanted to get a physical one rather than the esim I had been using since my previous phone was stolen., and it duly arrived on the 2nd September. At this point my phone was working fine on the old contract, and I had data.

I go to my o2 website and activate the sim - it claims to work. I put it in my phone - and it connects - but only to the cell network and I have no data at all. This seems very odd, I try various resets, no change. It's easy to tell there is no data as you never see anything like 3g/4g/5g in the connection bar, and of course no data goes through! The next day I contact support, they get me to try the usual resetiing things, of course nothing works. So they give me a new esim - exactly the same happens - phone and text work, no data. I end up going back to a physical sim. I contact support a couple more times - same happens. So by now its 5th September - I call support, explain it all yet again, and its raised as an issue and I get a text saying I will hear form the tech team withint 3-7(!) working days, not exactly quick when I have zero data and I am paying for unlimited. Anyway I do get a call from customer service over the weekend, and I at least get some credit back as I explain its still not working.

So this morning I finally get a call - and guess what, they just went through the exact same steps as support already had, reset the mobile network settings, make sure it's all enabled, I explain other sims work in this phone, and if I try this sim in another phone it shows the same, so it's clearly not the phone. I keep mentioning it must be something odd with the account or some data bar or something, but okay, I follow the instructions, the last thing they say is do a reset of the network settings (which I had tried twice the week before) and someone will call you back in an hour or so to see if that helped. It o course did not, and its not 6 hrs later and still no call back. I am not sure what else I can do - every time I call I get sent round the same loop - the fact is I have had zero data sine my so called "upgrade" to a new 2 year contract...

I look at my account and it says I have unlimited data

Though I notice it looks a bit odd when I click view allowance

Surely Unlimited should not say 0 mb?

Anyone got any suggestions what I can do next? if I call 202 I just get the same response every time, and they say someone will get back to you, which they may or may not do. Having just signed a new 2 year contract I am clearly very unhappy - though I guess I can argue they are not keeping the contract, which might invalidate it.

It's frustrating - I have had to buy a data sim (from another provider after this mess) as I need my phone for work purposes, and soon I go abroad for a while and need my roaming data back 😞

Thanks for any suggestions - my only remaining thought is to submit some official complaint, but that will take ages I am sure and still not actually resolve my issue.

Have you tried changing the APN to 'mobile.o2.co.uk' in the network settings?

Note the small 'o' in o2

Yeah that's one of the many things that was tried on the phone, the APN settings all look correct.

They called again, asked all the same questions again and again it is getting sent to the technical team who might respond in another 3-7 days...
